I hope they come to the conclusion that Alan Taylor's 2 hr 30 min running would be best for the film. T:TDW only being 10 minutes longer than the first film would probably hurt it especially since there's so much stuff to pack into the movie.

On another note, from the sounds of that book they really are making the dark elves sound badass and they're building them up nicely. Because honestly based on their "look" they don't seem like they would be much of a threat to Thor. So I hope they have magical powers to go along with their weaponry, I don't want them to just rely on their lasers.
